Nodemanager and Spotfire Server - trust issues and clock synchronization
When trusting Nodes you have to make sure that the Node Manager and the Spotfire Server(s) machines have their clocks in sync. More than a few minutes out of sync will break the HTTPS communication between them.
Please note that this is regarding clock, not timezone - the UTC timestamp must be in sync, but the time zones can be different.
Set the clocks in sync manually or use Network Time Protocol (NTP) server to synchronize them.External link (explaining NTP):
